A growing concern is the depletion of TOPSOIL, which is essential for farming and gardening. TOPSOIL is a seven-letter word, FARM is a four-letter word, and GARDEN is a six-letter word. The loss of TOPSOIL can have serious consequences for food production, as it is the layer of soil that contains the most nutrients and is necessary for plants to grow. As such, it is important to take steps to protect and conserve TOPSOIL in order to ensure sustainable food production.
